    Study Notes

    Neuroanatomy

    • Study of the nervous system's various parts and their respective functions

    The Nervous System

    • Comprises many substructures, each consisting of many neurons with specialized functions
    • Each part works together to produce behavior, and damage to different parts results in distinct behavioral deficits
    • Acts as a network of neurons that generate, modulate, and transmit information between all parts of the human body
    • Regulates vital body functions, including:
      • Heartbeat
      • Breathing
      • Digestion
    • Responsible for:
      • Sensation
      • Body movements
      • Consciousness
      • Cognition
      • Behavior
      • Memories

    Prenatal Period

    • Begins at conception and ends at birth, lasting around 270-280 days or nine months.
    • Divided into three periods: Zygote (Germinal Stage), Embryo (Embryonic Stage), and Fetus (Fetal Stage).

    Period of the Zygote (Germinal Stage)

    • Lasts from fertilization to the end of the second week.
    • Characterized by the formation of the zygote (fertilized ovum).

    Period of the Embryo (Embryonic Stage)

    • Lasts from the end of the second week to the end of the eighth week.
    • Characterized by the formation of the first bone.

    Period of the Fetus (Fetal Stage)

    • Lasts from the end of the eighth week to birth.
    • Considered the critical period, as the newly formed individual becomes susceptible to damage and defects.

    Genes

    • True carriers of heredity.
    • 3000 genes per chromosome.
    • X and Y chromosomes determine sex.

    Hazards During the Prenatal Period

    • Physical hazards: starvation, lack of uterine preparation, implantation in the wrong place, miscarriages, developmental irregularities, and prematurity.
    • Psychological hazards: traditional beliefs, maternal stress, and unfavorable attitudes from significant people.

    Maturation and Fertilization

    • Maturation: the process of chromosome reduction through cell division.
    • Fertilization: occurs at conception, taking place within 12-36 hours, and results in the union of a sperm cell with an egg cell.

    Conditions Influencing Physical Hazards

    • Timing of their appearance.
    • Maternal malnutrition.
    • Maternal age.
    • Kinds of work.
    • Multiple births.

    Importance of Conception/Prenatal Period

    • Hereditary endowment.
    • Sex.
    • Number of offspring.
    • Ordinal position.

    Developmental Psychology

    • A branch of psychology that studies intraindividual changes and interindividual differences in developmental change.
    • Covers the life span from conception to death.
    • Explains physical, social, emotional, moral, and intellectual development over a person's life span.

    Laws of Developmental Direction

    • Cephalocaudal Law: development spreads over the body from head to foot.
    • Proximodistal Law: development spreads outward from the central axis of the body to the extremities.

    Development

    • A progressive series of changes that occur as a result of maturation and experience.
    • Characterized by qualitative changes.
    • Each phase of development has characteristics, hazards, and patterns of behavior.
